CLUTCH.

SPECIFICATION forming' part of Letters Patent No. 427,344, dated May 6, 1890.

Application filed December 21, 1889. Serial No. 334,523. (No model.

Our invention consists of a clutch formed' of a section fixed to ashaft, a sliding sleeve, a section loose on said shaft, and a 'system of levers for Operating the sleeve, whereby the Sections or parts may be quickly and effectively coupled or clutched, as Will be hereinafter set forth.

It also consists of pieces or facings of material inserted in the loose section for increasing the frictional contact of the other parts therewit-h.

It also consists of other novel features, as Will be hereinafter fully set forth.

Figure 1 represents a partial face view and partial sectional view of a clutch embodying our invention. Fig. 2 represents a longitudinal section thereof. Fig. 3 represents a section of a portion on line w w, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a shaft, on which is loosely fitted the pulley A' to the hub of which is secured the section B of the clutch.

C clesignates a Section which is keyed or otherwise secured to the shaft A, and is of greater diameter than the section B, and has a peripheral rim D, on which is freely fitted one liinb of an 'angular sleeve E, the other limb of which encircles the side of the section B near the peripherythereof. Passing through the side limb of the sleeve E and the section C near the periphery-thereof are sliding bolts F, whose heads bear against said limb and whose opposite ends are engaged by levers G, the fulcra Whereof are on lugs or projections H 011 the side of the section C. The heel ends of the levers G are engaged by the shoulders J of levers K, the latter being pivoted or mounted on the hub portion ofV thesection C and pivoted to links L, whichare pivoted o1- mounted on the sliding collar M of the chuck.

Inserted into the section B near the periphery thereof are seg'inents N, of Wood or other suitable material, the same having their sides or faces proj ecting outside of the said section, so as to come in contact with the side limb E' of the sleeve E and the portion C' of the section O, said portion proj ecting somewhat from the inner face of said section C, forming a contact-face for the segments N.

Encircling the bolts F in the space between the sleeve E and peripheries of the Sections B O are Springs P, which bear against the limb E' of said sleeve and the side of the section C, the tendency of said Springs being to separate said sleeve from the section B.

The operation is as follows: When it is (lesired to close the clutch, the collarMis moved, in the present case to the right. As the links L follow the motions of the sleeve, their tendency is to move the outer ends of the levers K in the direction from the sleeve, whereby the shoulders J at the inner ends of said levers are pressed against the inner ends of the levers G, the latter then turning on their axes or fulcra, so that their outer ends draw the bolts F in the directionof the arrow, the heads of the bolts being in contact with the outer face of the liinb E'of the sleeve E, as hasbeen stated. Consequently said sleeve is pressed against the facings N, and the latter is clamped between said sleeve and the section O and the section B, whereby the two Sections are foreibly clamped together or coupled. The inserted pieces N increase the frictional contact of the sleeve E With the section B, the result of which is evident.

It is evident that when the collar M is operated in reverse direetion the lever G is released, whereby the spring's P, which -have been compressed, are then operated, so as to separate the sleeve E from the section B, Whereby the clutch is opened or uncoupled.

In the motions of the sleeve E the peripheral riin E2 of the same is guided on the peripheral rim D of the section O.

The bolts F carry nuts Q for adj usting the position of the sleeve E.

Secured to the periphery of the section C and passing freely through the side of the sleeve E intermediate of the levers Gare pins R, which serve to guide said sleeve in its move- IOO ments to and from the section B and also conneet said sleeve and section C, so that they rotate together HaVing' thns described our invention, what we elainl as new, and desire to seenre by Letters Patent, is-

1. A fixed section, in combination with a movable section, a sliding' sleeve which is adapted to engage with the inovable section, bolts which connect the sleeve with the fixed section, the levers G K, and the links L, substantially as described.

2. A clut'ch having' a fixed section and a movable sleeve, bolts connected with the sleeve, the levers G K, Inounted 011 said seetion and eng'aging' with each other and the former with said bolts, the sliding eollar M, and the pivoted links L, connected with said collar and with the levers K, the parts named being combined substantially as described.

8. In a clutch having a fixed section C and a movable section B, a sliding' sleeve E, the pivotal levers G and K, for closing' the sections, both mounted on the section C, and the levers K having Shoulders .T, which eng'age with the heels of the levers G, substantially as described.

4. The section B, with a projectingfacing N, the sleeve E, and section C, said sleeve havin g a limb E', which is adapted to engage with one side of the faeing N, and said section O having` a projectingbearing-surface (J',wl1ieh is adapted to eng'age with the other side of said facing, and the levers G K and links L, the parts named being; combined substantially as described.

5. The Sections B O and sleeve E, in combination with bolts F, conneeting' the section O and said sleeve E, the levers K, the links L, the leVers G, Operating on projecting fulora, said levers being' in connectionwith said bolts for closin` said sleeve against the section O, and the spring` P, for separating the same, substantially as described.

G. The stationary section O and movable sleeve E, in combination with the gnide-pins R, which are seenred to the section O and pass freely through the said sleeve E, and the bolts F, substantially as described.

7. The seetions B O, sleeve E, bolts F, Springs P, collar M, and links L, in combination with eomponnd levers, snbstantially as deseribed.
